HELIUM II APPLICATION IN SPACE COOLING SYSTEMS.

Author(s) : KLIPPING G.

Type of article: Article

Summary

THE COOLING OF IR TELESCOPES REQUIRES TEMPERATURES BELOW 2 K FOR LONG TERM MISSIONS. THEREFORE HELIUM-II COOLING SYSTEMS ARE TO BE DEVELOPED WHICH PROVIDE A FAVOURABLE RELATION BETWEEN COOLING POWER AND THE AMOUNT OF COOLANT, UNIFORM TEMPERATURE DISTRIBUTION AND THE ADVANTAGE OF THE SPECIAL PROPERTIES OF HELIUM-II. A MOST IMPORTANT PART OF SUCH COOLING SYSTEM IS THE PHASE SEPARATOR WHICH MUST WORK RELIABLY UNDER ZERO G CONDITIONS. A NUMBER OF INTERESTING PROBLEMS OF HELIUM-II PHYSICS ARE TO BE SOLVED IN CONNECTION WITH THESE DEVELOPMENTS.
